The Free Ticket Deal

If this sounds familiar, it is. Last year, American Airlines ran a "Fly to the U.K., Earn a Free Companion Ticket to the U.K. or the Caribbean" promotion.

The deal: Now the qualifying dates have been extended. AAdvantage members who book round-trip first class, business class or select economy class fares between the U.S. and Britain and travel by March 31 will receive a free companion ticket for future travel to Britain or the Caribbean until Dec. 31. Enroll as an AAdvantage member and use promo code "UKCMP" to get the deal. There are more than 30 Caribbean destinations to choose from.
